Report: WR Robinson coming in for workout

Laurent Robinson, who’s upstart career came to a concussion-laden halt last season, is coming to work out Thursday for the receiver-thin 49ers, as first reported by the Boston Globe’s Ben Volin.

Robinson is a six-year veteran who’s played on four teams, and he was limited to seven games with the Jacksonville Jaguars last season due to multiple concussions.

The 6-foot-2, 205-pound wideout produced 11 of his 15 career touchdowns during a breakout, 2011 season with the Dallas Cowboys. He previously played with the Atlanta Falcons and St. Louis Rams.

The Miami Dolphins on Tuesday worked out Robinson, who also has auditioned for the New York Jets, New England Patriots and Detroit Lions.

The 49ers’ receiver depth is being tested as leg injuries continue to sideline Kyle Williams, Mario Manningham, A.J. Jenkins and Kassim Osgood. Michael Crabtree is also likely out through at least November with an Achilles issue.
